You can dump it and plug it. I did this on my 5.2 swap. I actually swapped in a 98 intake, which already has the EGR plugged up, and welded the bung on the headers closed. Then I cut out all the wiring. Everything runs fine. The computer will store a code for fault in the EGR circuit, but it will not turn on the MALF light, if you are using one. I have one hooked up for troubleshooting while still shaking down the system.
